Fetal Heart Rate Labor. Fetal heart rate is 170 to 180 bpm. Baseline fetal bradycardia the absence of decelerations in the second stage of labor and marked accelerations coinciding with uterine contractions may suggest a maternal heart rate rather than an. Continuous fetal heart rate monitoring is widely used during labor even in low risk pregnancies. Baseline fetal heart rate definition average fhr rounded to 5 bpm during a 10 minute period but excludes periods of marked increased fhr variability segments of baseline that differs by more than 25 bpm must compromise at least 2 minutes out of 10 minute segment normal range is 110 160 bpm nichd always documented as a range.
The root mean squared error compared with fetal scalp electrode derived fetal heart rate was 4 8 2 0 bpm for noninvasive fetal ecg and 14 3 8 2 bpm for ultrasound. Auscultation is a method of periodically listening to the fetal heartbeat. Maternal heart rate patterns recorded by electronic fetal monitors closely resemble fetal patterns. Fetal tachycardia with possible onset of decreased variability right during the second stage of labor. The normal fhr tracing include baseline rate between 110 160 beats per minute bpm moderate variability 6 25 bpm presence of accelerations and no decelerations.
